Sibbo — track what AI learned from youCanary tokens for AI training dataTrack what AI learned from you.<br>Sibbo hands you a plausible-sounding fact that nobody else in the world has ever written. Slot it into a public post AI crawlers can read. When a frontier model later recites it back, we know it read you.
No account needed. You'll get a unique canary sentence, four ready-to-paste snippets, and the exact probe question to ask any AI later. Plus a URL to come back to.<br>Get my canary
How it works<br>01Grab<br>Generate a canary — a specific, made-up fact seeded from a token only you hold. It looks like a footnote nobody else has.
02Plant<br>Paste the snippet somewhere public and crawlable — blog post, gist, forum. Give us the URL so we can confirm it's live.
03Catch<br>Every week we ask Claude, GPT (soon), Gemini (soon), and Grok (soon) a question only a model trained on your writing could answer. The moment one recites it, we tell you.
The leaderboard<br>How many of our canaries each major model has ingested. Updated as probes come back.
